radeon_fence_check_lockup(9)
π radeon_fence_check_lockup π
okay so bestie, welcome to radeon_fence_check_lockup, a page from the Kernel API Manual πβ¨ this one's a tiny lil function with main character energy β it literally just peeks at your GPU's fences and goes "hmmβ¦ u good??" when things go quiet. let's get into it π«Ά
β¨ NAME β¨
radeon_fence_check_lockup β checks for hardware lockup π
(yes that's it, that's the whole gig)
πΈ SYNOPSIS πΈ
void radeon_fence_check_lockup (struct work_struct *work );
like, that's the whole signature. no return value, no drama, no notes π
π ARGUMENTS π
workβ the delayed work item π this is the thing that got scheduled to run later and now it's finally showing up to do its little job. icon behaviour tbh.
π¦ DESCRIPTION π¦
so what does it actually do, you ask? π§
It checks for fence activity β and if there is none, it goes ahead and probes the hardware to see if a lockup occured. π¨π
that's it. that's the function. it's giving "lifeguard at the pool who only jumps in when nobody's moving" πβοΈβ¨
ngl the whole point is: quiet fences = sus. so it pokes the hardware to find out if the GPU has properly frozen up or if everything's chill. it doesn't fix anything, it just checks. periodt. π
π SEE ALSO π
the kernel file itself lives at:
./drivers/gpu/drm/radeon/radeon_fence.cπ

likeβ¦ that's an entire friend group and this function is the one who texts "you up?" when nobody's replied in five minutes ππ«Ά
and that's the whole page, bestie!! π this one came from the ./drivers/gpu/drm/radeon section, dated October 2026, and it's filed under radeon_fence_check_lockup(9) β go forth and check those lockups, ily, bye!! ππβ¨
